I've a got q strange bug with one of my files. I am trying to convert a .prc into a .lrf, and if I convert using Calibre, it only works if I don't try to change any of the title and author information.

As soon as I input these, either in the convert dialogue or in the main window, the file seems to get corrupted (I can't preview it or send it to device anymore). If I convert and transfer it to the PRS without changing the title and author, and then try to modify it, the reader refuses to recognise the changes.

Anyone would know where that could come from?

Are you putting any kinds of special characters in the fields, like quotes, comas, ampersand, etc? If so, try it without those.
